The Avengers and their cowboy friends assault Kang’s fortress. While the other heroes fight Kang’s forces, Doctor Donald Blake, dressed as a cowboy with a fake beard, sneaks past the fight to reach Kang himself, before transforming back into Thor.

Thor wales on Kang so badly that the would-be conqueror panics and unleashes so much power that he reduces himself to atoms. With Kang dead, Immortus discorporates.

Thor’s comrade in the Avengers, Hawkeye has been lost in the past after a run-in with Kang the Conquerer. Thor has traveled into the past to rescue him alongside Moondragon, a recent addition to the Avengers. They are joined by Immortus, who has seemingly reformed and who also claims to be an alternate incarnation of Kang.

Thor and his compatriots have ended up in the year 1873 where they immediately encountered a posse of colorfully dressed cowboys. Amongst the posse’s number are Kid Colt, the Two-Gun Kid, Night Rider, and the Ringo Kid. The cowboys let slip that they know where Hawkeye is, and Thor angrily proclaims to the gunslingers that he dislikes firearms and gives a show of force before commanding that they take him and his allies to Hawkeye.

They catch up with Hawkeye, who fills them in: Kang has used future technology to conquer the town of Tombstone as part of his larger plan to get a head start on conquering the 20th century. And so the time-displaced Avengers dress up in semi-period authentic garb and set to foiling Kang’s plans, cowboy style.

While Thor has been fighting the Mangog, Captain America and the Avengers, currently consisting of Goliath, Wasp, Hawkeye, and the Black Panther, have been meddling with time travel. They now return to what they believe to be the present day, only to discover that the world that they have returned to is not the world from which they left. In the timestream they now find themselves in, the original Avengers, consisting of Thor, Iron Man, Giant Man, The Wasp, and The Hulk, have sized control of the world, capturing and indefinitely detaining all other people with super powers, be them hero or villain.

Of course, these alternate Avengers are being manipulated by Kang the Conquerer but he isn’t mind-controlling them, nor is he blackmailing them, simply giving them a thin pretense of heroics under which they can justify world-rule. Kang posed as an alien on a mission of peace, and offered to cure all of Earths ills if the Avengers would first imprison all other superhumans. They unanimously accepted his offer without even asking for the slightest evidence to back his claims.

The specifics of how things play out don’t much matter as this is a time travel story that ends with the erasing of all memory of occurrence on the part of all participants. Nonetheless, it stands as sharp reminder of how little it takes to get Thor to conquer the planet, as he has done or attempted to do at least twice in the past.

Fresh from his victory in the Great Troll War, the Warlord of Asgard is ready to return to Earth. Sif wants to accompany him but Thor gives her the brush off. He claims that his heroing on Earth is man’s work. Even after Sif shoots that down as a load of bull, he still insists on going by himself.

Thor has started to think about all that has gone on recently and he is a confused god. He really likes Sif but he remembers that he until very recently felt that way about Jane. He wonders if Odin altered his brain to make him move on from Jane to Sif or if Sif is really that awesome. It is very confusing to him. One thing is for sure, Doctor Donald Blake’s life has gone to shit. Thor decides that what is called for is to rebuild what he has let fall apart.

He returns to Earth and once again transforms into Doctor Blake. Apparently, he has physician friends and apparently they filled in during his absence. He tries to get his files in order, discussing his return with Olsen the janitor.

Meanwhile, archaeologists have discovered a living man who was the size of a doll when first found, but who has steadily grown larger and larger whenever he is touched by another person. He wakes and goes on a rampage, soon becoming the size of a small mountain.

This Growing Man is alarmed for he does not know his purpose. He seeks his master so that he can be told what his purpose is. This is a poignant and philosophical and undeveloped notion.

It turns out that the Growing Man is a Stimuloid created by Kang the Conquerer and was hidden in Kang’s past to serve as a sleeper agent for attacking his enemies in the future. Unfortunately he was awoken too soon. Kang has thus returned to the primitive 20th century so that he might re-shrink his weapon.

Thor tracks down the Stimuloid and oddly is able to recognize him as being one of Kang’s creations from the far future, which is odd since none of Thor’s past on-page interactions with Kang have involved Stimuloids. There are any number of ways Thor could have picked up this knowledge but it is still strange.

Thor fights Kang and the Stimuloid until they retreat to Kang’s time machine. Before they can escape, Thor throws Mjolnir (here spelled “Mjolnar”) so hard that it spins around the time machine at a speed greater than light, trapping the time machine in a Universal Infinity Vortex, causing a cataclysmic displacement trapping Kang and his Stimuloid beyond all time and place.

First Appearance: Stimuloids, The Universal Infinity Vortex, Olsen the Janitor
